Costain has been selected by Transport for London (TfL) to join its Infrastructure Improvement Framework.

The multi-discipline framework, covering both design and construction, will allow for major infrastructure upgrades across the capital. This includes upgrade work at South Kensington tube station and works to enable TfL’s step-free access programme.

Costain was one of three successful suppliers joining the framework, which carries a total value of approximately £700m. Projects will be awarded over a two-year term, with an option of a two-year extension.

Drawing on its extensive cross-sector experience delivering complex transportation infrastructure programmes, Costain’s role will see it provide a range of best-in-class services, including design, engineering, programme delivery and supply chain management.

The framework award extends Costain’s long-term delivery of complex infrastructure with Transport for London, including using production thinking, which combines modern methods of construction with new technologies, to successfully refurbish the A40 Westway, one of London’s busiest routes.

Alex Vaughan, Chief Executive at Costain, commented: “We are a trusted, long-term partner of Transport for London, and our growing relationship with this important customer is testament to our proven track record in delivering best-in-class infrastructure services across the capital.

“Upgrading London’s transport network is critical for a more prosperous, resilient and decarbonised UK. We look forward to bringing our capabilities in engineering, design and construction to deliver high-impact projects on time and on budget, underpinning London’s growth for future generations.”
